Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 256

A minimal faithful permutation representation — 4 generators on 28 points:

(1,2)(3,4);(6,9,11,12)(13,14,16,21,18,15,25,22,20,24,27,26,19,23,17,28);(5,6,10,9,8,11,7,12)(13,15,18,14,20,23,19,24)(16,21,25,28,27,26,17,22);(2,4)(6,11)(9,12)
